Roy, U., Shaha,B.K., Mazhabuddin,Kh., Haque, M.F., Sarower, M.G. 2010. Study on the diversity and seasonal variation of zooplankton in a brood pond, Bangladesh. marine.res.aqua. 1(1):30-37. The present study was designed to estimate zooplankton abundance qualitatively and quantitatively in carp brood fish culture systems. Plankton samples were collected from Gallamari fisheries extension & training centre farm, Batiaghata, Khulna, one time in a month. A total 6 groups of zooplankton were found from the study ponds. The identified zooplanktons were under six orders namely copepoda, rotifera, cladocera, ostracoda, crustacean larvae and bryozoa. Numbers of zooplankton groups were recorded to be the highest in December. In the brood pond copepod was the dominant order. Among various orders of zooplankton, the percentages of copepoda, rotifera, cladocera, ostracoda and crustacean larvae brysozoa in brood fish culture system were 55%, 8%, 25%, 9%, 2% and 1% respectively. Copepoda was domi...
